studies
Below
are some examples of how Benchmark Performance has transformed its
clients' I.T. systems, producing real business benefits:
Inmarsat
Limited
(the International Maritime Satellite Organisation) needed to upgrade
its corporate data warehouse. Benchmark Performance specified, installed
and configured a new warehouse server consisting of a hybrid cluster
pair of Alphaserver ES40 and ES45 attached to an HSG80 SAN controllers
supporting over 1TB of storage. The front end uses Brio while the
backend database uses Oracle 8.1.6 now migrated to 8.1.7. Inmarsat's
warehouse is mission critical as it holds commissioning and billing
data for all traffic over Inmarsat's satellites and provides quasi
real time updates to the cubes using replication from the billing
system. As the server has been very successful, vastly outperforming
the previous warehouse, Inmarsat has asked us to conduct tests for
9.2.0.1 with a migration planned early in 2003.
Acco
plc
is the leading maker of office products holding brands such as Rexel
and Twinlock. Its European operations are mostly run using the Baan
ERP suite though a few sites still use legacy systems (IMPCON, SOP)
running on RDB. Benchmark built its European datawarehouse on an
ES40 using the last of the generation of SCSI attached storage (HSZ80).
This project is notable because of the large amount of optimisation
that we carried out to fit monthly and daily builds during the allowed
time windows. It is the only project where we were able to outperform
a simple SAME architecture (Stripe And Mirror Everything) by using
a carefully designed database on hardware mirrored individual disks.
The database in this project was Informix.
KPMG
asked Benchmark to configure a data warehouse for a client consisting
of a pair of Alphaserver ES40s running Oracle. The client is a leading
Internet micropayments company. Benchmark worked alongside KPMG
to translate their business specifications for the warehouse into
the physical and logical design of the warehouse. Because of limitations
of the schema of the OLTP source system, this warehouse was only
able to offer nightly updates. Front end cube building and drilling
down was carried out using Broadbase - specified by the end client.
Benchmark
won the open tender in 2000 for the migration of the ESAS commissioning
system VMS to Tru64 server migration at Inmarsat
Limited. The project involved the migration of scripts,
libraries and programs from one operating system to the other as
well as the database migration from Oracle 7.1.3 to Oracle 8i. This
project was awarded at fixed price and was completed successfully
and on time. This migration was absolutely mission critical for
Inmarsat as the much larger project for web-enabling the front-end
(ESAS2000) depended on using an Oracle 8 feature (Advanced Replication)
between the back-end server and the web. Once the port was complete
Benchmark was awarded the contract for the specification, procurement
and implementation of the new servers as well as the project to
cut-over to them. ESAS data is sent to many Inmarsat customers round
the world who use it in their own systems: Land-Earth Stations (LESO)
in particular. Because of this, a rollback from an unsuccessful
cut-over would have been extremely difficult. It was crucial, therefore,
that the migration be accurate and rapid. The project was very successful
and the careful specification of the servers we carried out means
that they now comfortably support 3-legged advanced replication
to two external websites as well as snapshot replication internally
to other servers on the Inmarsat LAN. This is a considerably higher
load than had been specified in the Inmarsat RFP at the time. This
database is extremely important as it holds all the distress and
safety at sea information of maritime traffic and we currently hold
the out-of-hours support contract for ESAS.
Benchmark
configured a SAP cluster and SAN for Norton Healthcare
that went live in the Spring of 2001. It consisted of a pair of
Alphaserver ES40s running SAP over Oracle as well as additional
Alphaserver DS20s as SAP application servers. The cluster was supported
by an HSG80-based SAN mirrored between two sites. The cluster and
the storage were set up in such a way that the full SAP service
could survive the total loss of one site. As the cluster supported
several other remote sites and ran the entire business for Norton
Healthcare it was absolutely mission-critical. The configuration
uses Tru64 5.1 and HSG80s with multibus failover.
Coconut.com
is an internet company running Intermail software to provide webmail
access to the public and corporate clients. Intermail is an Oracle
8i application which stores email in the filesystem and data pointers
in an Oracle database and is the leader in WebMail applications.
Benchmark configured Coconut's ASP Clusters and SAN. The configuration
was huge though slightly old fashioned due to software constraints.
TheTru64 4.0F clusters did not support multibus failover and therefore
needed special care when attaching to a Fibre-based SAN. The project
consisted of 22 Alphaservers split in several TruClusters, with
a total configured storage of 2.5TB, fully mirrored. In this case,
the mirroring was local and not between sites.
Accucard.com
is part of a new breed of web-based credit card companies which
allow full account management of customer credit cards over the
Web. Accucard provides backend infrastructure to a number of credit
card providers which then concentrate solely on the branding - Stelios
Haji-Ioannou's EasyCard is possibly the best known. Benchmark configured
the Accucard data warehouse on a clustered pair of Alphaserver ES40
supported by an HSG80 SAN. The disk layout consisted of a combination
of faster and slower disks to optimise the price/performance of
the configuration. Oracle Advanced Replication was used to feed
the data warehouse from the live OLTP systems while, concurrently
providing a ready-made database for Disaster Recovery.
